Lanes-a PYROTEGHNIC SPINNING WHEEL.

Application inea september 4, 1925. ysemina. 54,512.

This invention relates to a pyrotechnic spinning-wheel of such construction that it may be folded to occupy a limited space for convenience and economy in making shipments; also includes such a construction that the pyrot'echnical devices carried by the spokes may be protected from injury during shipments. In the matter of these shipments, and particularly of thelarger sizes, the expense in providing large, strong boxes required for packing, has been found to be an item almost prohibitive. Another object of the present invention isV to provide a spinning-wheel of few and simple parts which may be conveniently folded for packing and which may be readily extended to normal form by the user.

`With the foregoing objects in view the invention presents a novel and useful construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawing, it being understood that changes in form, size, proportion and minor details may be made, said changes being determined by the scope of the invention as claimed.

In the drawing, which illustrates one emf bodiment of the invention, Fig. 1 is a front view of the spinning-wheel, the spokes being extended. Fig. 2 shows a side view of the hub, the spokes being folded. Fig. 3 is a broken away detail showing a plan or front view of the hub and spokes.

Referring nowl to the drawing,.numeral 4 indicates a hub of any suitable form adapted to be pivotally mounted upon an upright support 5, a pin 6 engaging in an aperture 7 formed centrally in the hub being shown for said mounting.,

Numerals 8 indicate recesses which open on the top and sides of the hub, and at 9 are indicated spokes, these being provided with pyrotechincal devices l0, and adapted to be disposed radially of the hub with their inner end-portions engaging in said recesses. Hinges 11 may be employed for connecting the spokes with the hub, and as thus described, the spokes, after being swung outwardly, may be maintained in the position shown in Figs. l and 3 by means of fastening-elements or catches v12 which operate to confine the inner end-portions of the spokes to the recesses 8; and, as is obvious, by moving the catches for permitting a release of said spokes from the recesses,

said'sp'okes, after being released,` maybe moved toward each other into folded relation in the plane of the hub, as shown in Fig. 2 of the drawing. Numeral 13 indicates a projection which is disposed centrally and extends beyondthe bottom of the hub to prevent undue friction of the hub, and preventing any Contact of the hub with the support 5 while the device rotates 0n the pin 6, rotation of the wheel as usual, being caused by the elements 10 when ig# nited.

It will be appreciated that the construe# tion now shownis adapted to effect a material saving in a manufacturers expenses, for, according to the regulations of express companies relating to the carriage of pyrotechnical products it is necessary that the boxes be made of strong lumber, and therefore the heavy weight for packages oontaining the spinning-wheels together with the high rate provided for the inflammable class -tends to make those shipments imprac tical. The invention therefore broadly includes spinning-wheels adapted to be folded at the factory to occupy a very limited space for shipments and adapted to be readily and conveniently extended by the user when ready to be exhibited.

I claim as my invention,-

l. In a pyrotechnic spinning wheel, a hub, spokes mounted on the hub to permit move ments of approximately 90 degrees to a right angle to said hub and to have swinging movements to be disposed radially of the hub, and pyrotechnical devices carried by the spokes'.

2. In a pyrotechnic spinning wheel,a hub, spokes for supporting pyrotechnical devices, each spoke having a pivotal mounting to permit it to swing from the hub in an are of approximately 90 degrees.

3. In a pyrotechnic spinning-wheel, a hub having recesses opening on its side and periphery, spokes pivotally connected with the hub and adapted to be moved into said recesses to be disposed radially of the hub, and fastening means for maintaining the spokes radially of the hub.

4. In a pyrotechnic spinning-wheel, a hub having recesses opening on` its side and periphery, spokes mounted on the hub, pyrotechnical devices on the spokes, said spokes being adapted to Vbe disposed radially of the hub while engaging insaid recesses and adapted to be swung .intov folded relation outwardly of the top of Vthe hub;

V5. In' a pyroteehnic spinning wheel, a hub arranged to have a pivotal mounting to permit rotation thereof, a plurality of spokes loosely connected with the hub for supporting pyroteohnical devices, said spokes being movable'to positions approximatelyat right angles to the hub to permit their outer ends to be disposed closely adJacent to each other,
